How effective is Virtual Colonoscopy in screening for polyps
Most studies suggest that the accuracy of CTC is greater than barium ememas and approaches optical colonoscopy, especially for polyps > 10 mm if the colon is properly prepped and distended. However, interpretation of CTC exams requires the review of both 2D and 3D images and it is recommended that only radiologists with experience evaluating 50 or more CTC exams should provide the interpretion.
